It is no surprise that being a teacher involves telling people things that they don't know. This can range from a simple addition of new knowledge - by far the easiest for the student to integrate - to the shifting of concept or understanding, which is much harder for any student to do.

Anytime we have to reorganize our belief system or reconfigure how we look at a problem, it requires significant effort and faith from us. This is largely due to our "confirmation bias," a mental phenomenon which causes all of us to adopt beliefs that confirm what we already think and ignore anything that conflicts.

​As teachers, we always have to tread lightly when correcting people, since they are doing the best they can, using every ounce of their intelligence to be all they can be. When we step in and tell them that they are doing something wrong, we can unknowingly tread on deep-held beliefs and long-held habits. Every time we correct a student, we are basically telling them they are wrong, which no one likes to hear. We can put our students on the defensive through the simple act of trying to help them.

For the student, it is rarely as simple as just changing what they do and how they think, which is why students often adjust to our instruction in the moment and then go right back to doing what they were doing. In these instances, we have not made any progress in instructing the student, since they have not made any progress in their understanding.

The way around this is not to avoid correcting our students, but to approach them like we are on their team instead of a superior who is "fixing" them. We must keep in mind that they are doing what they think is right. If they knew they were doing something wrong, they would change it immediately. We are not "correcting" them, but giving them an opportunity to improve. And who doesn't readily accept an opportunity to improve?
